An immediate infusion of federal funds would help save struggling Brooklyn hospitals that may not otherwise stay open past February, Gov. Andrew M. Cuomo and Mayor Bill de Blasio said Monday.

State funds for Long Island College Hospital, for example, may not be available after next month, Cuomo warned. He called for the U.S. Department of Health and Human Services to approve a $10 billion Medicaid waiver request that would help the hospitals.

Federal officials Monday pointed to a letter sent last week from U.S. Health Secretary Kathleen Sebelius to Cuomo that said their teams were working toward an agreement. The revised request seeks to broadly help Medicaid recipients and low-income patients, but the funds should not go toward determining the "future path" of specific hospitals, she wrote.

Several proposals to replace Cobble Hill's LICH, which has more than $500 million in liabilities and is run by the State University of New York, include a complex with an outpatient care center and housing units.

"Efforts to reach a compromise agreement allowing another entity to provide health care services in the LICH community are ongoing," SUNY spokesman David Doyle said.

Bedford-Stuyvesant's Interfaith Medical Center also faces financial troubles and may be forced to shutter.
